SPECIFICATION forming part of Letters Patent No. 438,101, dated October '7, 1890.

Application filed J une l2, 1890. Serial No. 355,155. (No model.)

To @ZZ whom it may concern,.-

Beit known that I, HENRY DARCUs, a citizen of the United States, and a resident of Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Lamp-VVick-Adjusting Devices; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of the lamp in perspective. Fig. 2 is a vertical central section of same. Fig. 3 is a view in detail.

The object of this invention is to provide eiiicient means for moving alamp-wick up and down while guarding the movement in such a manner as to avoid accidental displacement of the wick; and the invention consists in the construction and novel combination of devices, all as hereinafter set forth.

In the accompanying drawings I have illustrated the invention in its application to an annular wick, while it may be as readily applied to the flat-wick construction.

The letter A designates the annular wick, which in the construction illustrated moves up and down upon the central guide B. Around the wick is the perforated or rack portion or tube or cylinder C, which is free to move up and down, except that its motion is limited by the spring-lever D when the latter is in engagement therewith.

E represents the jacket-piece above the lamp-bowl, carrying the outer wick tube or cylinder F, in which the adj Listing-rack cylinder C moves, the upper margin of the wickcylinder F, which is also the extinguishing cylinder, being illustrated at a.

The spring-lever D is horizontal and is made capable of movement of reciprocation inward and outward in the direction of its length, and it is pivoted on a fulcrum at b of the jacket-piece. This lever projects through the jacket-piece inward radially and through bearing d for engagement with the fulcrumpin b, the slot being of sufficient extent to permit the lever to be pulled outward clear of the perforations of the friction wick-raising cylinder C. At its inner end the lever is provided with one or more teeth e, which serve to engage the perforations or catches of the cylinder C when said lever is at its inner adjustment, which is its normal position, and in which it is held by a spring S, usually located between the cylinder F and the outer wall of the jacketpiece,theinner end of said spring engaging a cross-piece orstop hof the lever. This adjusting-lever can be readily disengaged from the wick-carrying cylinder to allow the latter to be removed for cleaning or other purposes. The lever is in such position that it can be readily seen and cleaned, in fact, being located in the jacketpiece, it is not liable to become clogged or soiled to any extent. The limit of movement of this lever constitutes a regulator, as it provides for an accurate and determined movement of the wick upward to position for burning, without allowing it to rise to too great an elevation. So, also, it regulates the extinguishing movement of the Wick downward, providing just enough motion to allow the wick to be carried below the margin of the eXtinguishing-cylinder F without allowing it to descend into the body of the lamp. While it is a very simple wick-adjuster, it is also adapted vto prevent serious accidents. The friction-cylinder being freely adjustable when the spring-lever is pulled outward, may be located sufiiciently below the upper end of the wick to provide for considerable burn` ing away before a readjustment of the cylinder on said wick is required.

Having described this invention, what I claim, and desire tqsecure by Letters Patent, is y The lamp-wick-adjusting device comprising the central guide-tube, the jacket-piece above the lamp-bowl carrying the outer wick tube oli cylinder, the rack-cylinder arranged In testimony whereof I affix mysignature in presence of two Witnesses.

HENRY DARCUS.
